Load characteristics reference setting (Pr.1481 to Pr.1487)
• Use
Pr.1481 to Pr.1485
to set the reference value of load characteristics.
• Use
Pr.1486 Load characteristics maximum frequency
and
Pr.1487 Load characteristics minimum frequency
to set
the output frequency range for load fault detection.
Automatic measurement of the load characteristics reference (Load
characteristics measurement mode) (Pr.1480)
POINT
POINT
• Perform measurement under actual environment with the motor connected.
• Set the
Pr.1487 Load characteristics minimum frequency
higher than the
Pr.13 Starting frequency
.
• Setting
Pr.1480 Load characteristics measurement mode
= "1" enables automatic measurement of the load
characteristics reference. (Load characteristics measurement mode)
• Use
Pr.1486
and
Pr.1487
to set the frequency band for the measurement, and set
Pr.1480
= "1". After setting, when the
inverter is started, the measurement starts. (When the
Pr.1486
setting is lower than the
Pr.1487
setting, the measurement
does not start.)
• The automatically measured load characteristics reference is written in
Pr.1481 to Pr.1485
.
• After the measurement is started, read
Pr.1480
to display the status of the measurement. If "8" appears in the tens place,
the measurement has not properly completed.
• While measuring automatically, the During load characteristics measurement (Y213) signal is output. For the Y213 signal,
assign the function by setting "213 (positive logic)" or "313 (negative logic)" in any of in any of
Pr.190 to Pr.196 (Output
terminal function selection)
.
